React.js Development Services
Build lightning-fast web applications using modern, component-based React architecture. SaaS dashboards, headless storefronts, internal tools, real-time apps.
When to hire us for this
Everythingthatshipswithevery engagement.
No surprise add-ons. No phase two for the basics. The list below is the floor, not the ceiling.
React + TypeScript
Type-safe component architectures with strict TypeScript. Predictable refactors, fewer runtime surprises, and an editor that helps your team move faster as the app grows.
Next.js for SSR, ISR, edge
Next.js App Router with SSR, ISR, and edge-rendered pages where they pay off. Fast first paint, great SEO for marketing surfaces, and stateful app shells where users live.
Design systems with Tailwind, Radix, shadcn
Custom design systems built on Tailwind, Radix UI primitives, and shadcn patterns. Accessible by default (keyboard, focus, ARIA) and tuned to your brand, not a template.
Backend integration
REST, GraphQL, tRPC, and real-time WebSockets. We integrate with your existing backend, or stand up a fresh one (Node, Supabase, serverless functions) when you need it.
Authentication done right
Auth0, Clerk, Supabase Auth, or NextAuth. SSO, social login, magic links, MFA, and role-based access. Sessions and tokens handled the way the provider intends, not glued together.
State management that scales
Zustand, Redux Toolkit, and TanStack Query for server state. We pick the smallest tool that fits the problem so onboarding new engineers stays a one-day exercise, not a one-week one.
Sixsteps,oneconversation.
Linear enough to plan around, flexible enough to do good work.
Discover
Working sessions with your product, design, and engineering leads. We map users, jobs, and the system you have today.
Strategize
Architecture decisions (App Router vs Pages, server components, data fetching, auth, hosting). Documented, with the trade-offs spelled out.
Design
UI work with Tailwind and shadcn, or implementation against your design files. Component library scoped to your brand and your patterns.
Develop
Component-driven build in React and TypeScript. PR reviews, tests for the parts that matter (auth, money, data), and weekly demos.
Launch
Performance budget, accessibility pass, monitoring (Sentry, Vercel Analytics), and a calm cutover. No mystery bugs on day one.
Support
Optional retainer for new features, dependency updates, and on-call coverage for production. Pause or cancel any month.
Tools we reach for, picked for fit (not fashion).

Real results from real engagements.
A snapshot of the react.js development engagements where DoodleWeb owned strategy, design, and engineering end-to-end.
Ursa Major
Ursa Major delivers mission-ready aerospace and defense systems across hypersonics, solid rocket motors, and space-based defense, leveraging additive manufacturing and modular architectures to produce scalable all-up rounds, engines, and SRMs faster than legacy providers. From throttleable, storable hypersonics to tactically responsive satellite propulsion and extended-range solid rocket motors, Ursa Major is powering the joint force with flexible, American-made systems for any mission, in any domain. DoodleWeb replatformed them onto Drupal 10 — shipping a procurement-grade marketing site with significantly faster page loads, restructured navigation for defense and government stakeholders, and an editor-friendly CMS that lets internal comms publish at the pace of an engineering organization. Shipped in 16 weeks.
Amplify AI
Amplify AI, a B2B SaaS startup, replaced a slow custom WordPress site with a Webflow rebuild from DoodleWeb. Outcome: 4× demo bookings in the first 60 days post-launch, demo-to-customer rate up 60%, and a marketing team that ships pages independently without engineering involvement. Shipped in 10 weeks.
Young Americans Center
Young Americans Center, a nonprofit operating both a financial-education program and a youth-focused bank, unified two previously disconnected sites onto one WordPress platform on WP Engine. Outcome: a single high-impact brand story, editorial controls that respect the boundary between mission and product, and a platform an in-house team can extend. Shipped in 18 weeks. WCAG 2.2 AA conformant.
SiteSonar
SiteSonar is a DoodleWeb-built product: a no-code website performance adapter that lifts AI-search (GEO/AEO) visibility, identifies high-intent traffic, and converts more pipeline — without rebuilding the underlying site. Starts at $99/month, installs in 14 days, requires zero CMS migration. Used by marketing teams that need AI-search citation share without a replatform.
